We study the impact of air pollution on labor supply and wage compensations in Italy. Matching administrative data on the universe of Italian dependent employees in the private sector with \({\hbox {PM}}_{10}\) concentrations and weather data at monthly frequency, we exploit exogenous variation in wind speed to instrument for endogenous air pollution exposure. We find that a one standard deviation increase in \({\hbox {PM}}_{10}\) level, leads to a 7.3% higher probability of sick leave and to an earning loss of 0.83 euros/worker/month. These figures generated total social excess expenditures of 755 million euro during the period 2011–2016 considering a pollution threshold set by the World Health Organization and extending the effects to the total workers population. The heterogeneity analysis shows that the impacts are larger for workers in constructions and services, for white and blue collars and for females and foreign workers, while we find no impact on managers. The sick wage received by exposed workers is not always aligned to the pollution exposure actually faced by different worker categories.

我们研究了空气污染对意大利劳动力供应和工资补偿的影响。将私营部门意大利受抚养员工的行政数据与\({\hbox {PM}}_{10}\)浓度和每月频率的天气数据相匹配，我们利用风速的外生变化来检测内生空气污染暴露。我们发现\({\hbox {PM}}_{10}\)增加了一个标准差水平，导致病假可能性高 7.3%，收入损失为 0.83 欧元/工人/月。考虑到世界卫生组织设定的污染阈值并将影响扩大到总工人人口，这些数字在 2011-2016 年期间产生了 7.55 亿欧元的社会超额支出。异质性分析表明，对建筑和服务业工人、白领和蓝领以及女性和外籍工人的影响更大，而我们发现对管理人员没有影响。暴露工人获得的病假工资并不总是与不同工人类别实际面临的污染暴露相一致。
